In the last few weeks, numerous high profile boxers have called for a fight with UFC superstar Conor McGregor.

Some of those boxers include WBO welterweight champion Jeff Horn, eight division champion Manny Pacquiao, and even Golden Boy Promotions CEO Oscar De La Hoya, who retired in 2008 and captured world titles in six weight divisions.

McGregor made his professional boxing debut back in August, when he stepped in the ring with five division champion Floyd Mayweather, 40 years old and snapping a two year retirement.

McGregor started very well in the fight, but faded as the contest played out and saw himself get stopped in the tenth. Not many had expected the contest to go that long.

The fight did tremendous business - with 4 million pay-per-view purchases, which is the second highest buyrate in PPV history.

McGregor is estimated to have made over $100 million when everything was said and done.

Whether it's boxing or MMA - UFC President Dana White has serious doubts about his star athlete ever fighting again.

"Listen … Conor might never fight again. The guy’s got a f***ing hundred million dollars," White told media members, according to MMA Fighting.

“These guys make money and that’s it. Fighting is the worst. Try to get up and get punched in the face every day when you’ve got $100 million in the bank. Money changes everything for a lot of people.”

White believes the huge payday for the Mayweather fight - was a likely contributing factor in McGregor's conduct at a recent Bellator event, when the fighter was very hostile and became confrontational after he illegally entered the cage and was asked to leave.

“He’s a young, rich kid who is a god in Ireland. That’s not the healthiest environment either. It’s all part of it. I don’t know if you guys remember in the very beginning with Jon Jones. There’s no doubt the talent was there. I used to go, ‘The guy is talented, but he’s young, he’s rich, he’s the king of the world now. Hopefully he can keep it together.’ That was way before the crazy sh*t started to happen. And there it is. It happens," White said.

“What’s weird is it happens more in this sport, in fighting, in the fighting business, more than any other sport.”
